  • Patent number: 6577127
    Abstract: A magnetic resonance imaging method is proposed wherein the MR signal acquisition is performed by separate scanning of central (40) and peripheral (70) sectors. Central and peripheral sectors are selected in an individual plane in the k-space and optionally an intermediate sector (50) between the peripheral and central sectors is also selected. The center (O) in the k-space in the individual plane at issue is situated within the central sector. The scanning of the k-space commences outside the center of the k-space and before or during increasing contrast. Preferably, the scanning is timed such that the center of the k-space is reached at maximum contrast (MR angiography) or at the value zero of the longitudinal magnetization (MR inversion recovery). The central sector is advantageously scanned in a stochastic order. The peripheral sector may be scanned along a spiral-shaped trajectory, radial trajectories or along high-low ordered lines.
